It's used for the NT4 sync feature of FSD, principally because otherwise a Windows version of FDS would have been required, and because modifying its functionality with plugins is quite easy (Java and SWIG). ApacheDS doesn't yet have the feature set that FDS has, but if you want a DS that runs on Windows and isn't from Microsoft, it could be an option for you. BTW it looks like Sun still ships their DS for Windows.
